Studies on fluorine containing condensation polymers are limited compared to that of fluorine containing addition polymers. In this report, highly fluorinated aromatic polyesters were synthesized by a polycondensation reaction of tetrafluorophthalic anhydride with ethylene glycol. Viscosity, solubility, thermal properties and crystallization behaviors of fluorinated polyesters were investigated using IR, 19F NMR, DSC, GPC, polarized optical microscope and rheometer. The fluorinated polyester is insoluble in most organic solvents, such as acetone, ethyl acetate, chloroform, THF, and trichloromethane. However, it is soluble in highly polar solvents, such as dimethylsulfoxide, dimethylformamide and dimethylacetamide. The fluorinated polyester (o-PETF) is a crystalline polymer with a crystallization enthalpy of 35.2 J/g and a broad crystallization temperature range from 54 to 130 C. Average crystalline growth rate is 4.2 mum/min at 110 C in the preliminary 30 min. Spherulite growth was observed at the temperature when the dendrites begin to melt. Crystallization property of o-PETF may be ascribed to the higher mobility of fluorinated polyester chains and dipolar contribution of carbon-fluorine bonds.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 1563-38-8

Synthetic Route of 1563-38-8, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.1563-38-8, Name is 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol, molecular formula is C10H12O2. In a article,once mentioned of 1563-38-8

An area of shore on Laysan Island in the Hawaiian Islands National Wildlife Refuge has been observed over the last 10 years to cause mortality to several species of birds, crabs, and insects which come into contact with the sand. Previous analysis of two composite samples from 1993 and 1997 indicated contamination of carbofuran in the sand at levels in the low mug/g range. In November of 1997, and July and October of 1998, 129 additional samples were collected in order to define the extent of the carbofuran contamination. Sand samples were extracted with acetone in a pressurized fluid extractor and analyzed by GC-MS. Localized contamination was present at 1,639 mug/g of carbofuran and over 8,832 mug/g of its primary breakdown product, carbofuran-7-phenol. In addition to carbofuran-7-phenol, four other known transformation products were observed in sample extracts, including 3-hydroxy carbofuran, 3-keto carbofuran, 3-keto carbofuran phenol, and carbofuran diol. Two additional compounds which have not been previously reported as carbofuran breakdown products were also found. Spectra are presented and structures are proposed for these two compounds. The structure of one compound, carbofuran acetate, was confirmed by synthesis and GC/MS. To assess relative toxicity, Microtox bioassays were conducted for standards of carbofuran, 3-hydroxy carbofuran, and carbofuran-7-phenol, as well as for water extracts of native contaminated and clean sand. These assays supported the conclusion that the toxicity at the site can be explained by the presence of carbofuran and its products.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Recommanded Product: 2-Methylbenzofuran. Introducing a new discovery about 4265-25-2, Name is 2-Methylbenzofuran

This paper describes tar destruction and coke (or soot) formation of biomass in three different conversion processes: pyrolysis (in a pure nitrogen stream), steam gasification (in a mixture stream of steam and nitrogen), and partial oxidation (in a mixture stream of oxygen and nitrogen), over a wide temperature range from 600 to 1400 C. A woody waste, hinoki cypress sawdust (HCS), was used as a feedstock, and an entrained drop-tube furnace (DTF) was applied to all experimental tests. It is found that raising the temperature remarkably decreases tar evolution. Steam and oxygen also have a positive effect on tar destruction. Benzene and toluene are the most difficult condensable tar species to destroy. The achievement of their complete destruction in the product gas requires extremely high temperatures above 1200 C, regardless of the gasifying agents. The coke deposits from 900 C and reaches a maximum formation at 1000 or 1100 C. The results obtained in this study suggest that competition occurs between the secondary decomposition of hydrocarbon species and gasification reactions of the produced char and/or coke with gasifying agents in the temperature range of 900-1100 C.

A manganese- and borane-mediated synthesis of isobenzofuranones from esters and oxiranes is developed. The reaction proceeded at aromatic, heteroaromatic, and olefinic C-H bonds with high functional group tolerance. This is the first example of a manganese-catalyzed C-H transformation using an oxygen-directing group. Triphenylborane played an important role in this reaction to cooperatively promote the annulation reaction. Kinetic isotope effect experiments revealed that C-H bond activation of the aromatic rings was the rate-determining step.

Titanium (Ti) and its alloys are widely used for medical and dental fields due to their excellent biocompatibility, high corrosion resistance, high specific strength and excellent mechanical properties. Different methods have been developed to improve the surface properties of titanium-based implant materials, and consequently the bone-bonding ability. The Ti-7.5Mo alloy was activated by an alkaline treatment with 5M NaOH, heat treatment and subsequent immersion in SBFx5 to investigate the in vitro response of osteoblastic-like cells (MG-63) on altered biomimetic surfaces. Sample surfaces were characterized by scanning electron microscopy. Cytotoxicity was assessed by the MTT assay, total protein content, alkaline phosphatase activity (ALP) and mineralized bone-like nodule formation. It was shown the que alkali treatment led to the formation of sodium titanate and immersion in SBFx5 formed a film of calcium phosphate. The alkaline treatment and heat treatment of 7.5 Ti-Mo alloys followed by soaking them in SBFx5 for 24 hours is a suitable technique once the final samples were biocompatible, allowed the attachment of the osteoblastic-like cells (MG-G3), and increased the mineralized like-bone nodules formation by these cells.

Two series of 2-substituted and three new diacetyl benzofurans were synthesized through palladium-catalyzed reactions and their in vitro antimicrobial spectra were assessed. The compounds demonstrated mild to significant growth inhibition against antibiotic-susceptible standard and clinically isolated strains of Gram-positive and Gram-negative bacteria as well as human fungal pathogens. Ampicillin and kanamycin were used as references for antibacterial screening; nystatin and amphotericin B were used for antifungal screening. Varying substitution at the benzofuran moiety and subsequent antimicrobial screening identified the C-3-acetyl functionality as a new structural alternative for optimal antimicrobial property in the benzofuran class of compounds.

In an article,Which mentioned a new discovery about 125-20-2

The viscosity properties of acetylated carboxymethyl starch (ACMS) aqueous solution with different DS (degree of substitution) at concentration of 2.0% (w/w) were investigated using Brookfield R/S+ Portable rheometer. All flow curves of ACMS are well fitted to Power law model. Arrhenius model was used to describe temperature sensitivity. Furthermore, the parameters, which influenced the viscosity properties of the solutions, including temperature, DS of carboxymethyl group (DScm), DS of acetyl group (DSac), presence of salt (NaCl) and shear rate were discussed in detail. Specifically, the viscosity-stability, salt-tolerance and shear-resistance of ACMS with DScm (0.76) and DSac (0.34) were compared with that of sodium alginate as thickener in food or non-food applications. The results indicate that the viscosity properties of ACMS (DScm = 0.76, DS ac = 0.34) were similar to that of sodium alginate and ACMS with DScm (0.76) and DSac (0.34) may be considered as a substitute for sodium alginate in certain application.
